📋 Before You Begin

• 🚗 Park your F-150 on level ground, shift to Park, and set the parking brake.
• 🧊 Let the engine cool for several minutes if it was recently driven.
• 💡 Open the hood and locate the air filter box on the passenger side of the engine bay.
• 📌 A shop vacuum is used to remove loose dirt from the air box so debris does not enter the engine.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the Hood

• Use your hand to pull the hood release lever inside the cabin, near the driver-side lower dash.
• Use your fingers to release the secondary hood latch at the front center of the hood.
• Raise the hood fully and make sure it is secure.

Step 2: Locate the Air Filter Housing

• Look on the passenger side of the engine bay for the large black plastic air filter box.
• The air intake tube runs from this box toward the engine throttle body.
• Take a phone photo first.

Step 3: Release the Air Box Cover Clips

• Use your fingers to flip open the metal retaining clips on the air filter housing cover.
• If a clip is tight, use a flathead screwdriver gently to pry the clip outward.
• Do not force the plastic cover. The clips should release with light pressure.

Step 4: Lift the Air Box Cover

• Use both hands to lift the air box cover just enough to access the filter.
• Do not pull hard on the intake tube or nearby wiring.
• You do not need to remove the intake tube for a normal filter change.

Step 5: Remove the Old Engine Air Filter

• Use your hand to lift the old engine air filter straight out of the lower air box.
• Notice which side faces up before removing it completely.
• Check the old filter for heavy dirt, leaves, oil, or rodent debris.

Step 6: Clean the Lower Air Box

• Use a shop vacuum to remove loose dirt, leaves, and debris from the lower air box.
• Use a clean microfiber towel to wipe the sealing edge where the filter sits.
• Do not let dirt fall into the intake tube opening.

Step 7: Install the New Engine Air Filter

• Use your hands to place the new engine air filter into the lower air box.
• Make sure the rubber sealing edge sits flat all the way around.
• The filter should not be bent, pinched, or sitting crooked.
• A flat seal prevents dirty air leaks.

Step 8: Reinstall the Air Box Cover

• Use both hands to lower the air box cover back into position.
• Make sure the cover tabs are seated correctly in the lower air box.
• Use your fingers to snap the metal retaining clips closed.
• No torque spec is required because the cover is retained by clips, not bolts.

Step 9: Final Visual Check

• Use a flashlight if needed and inspect the air box seam all the way around.
• Confirm the cover is fully closed and all clips are locked.
• Make sure no tools, towels, or packaging are left in the engine bay.
